Safety Precautions
CAUTION: To help prevent personal injury and damage to equipment,
•Read, understand, and follow all safety precautions and operating instructions. If the
operator cannot read English, operating instructions, and safety precautions must be read
and discussed in the operator’s native language.
•Wear eye protection that meets the requirements of ANSI Z87.1 and OSHA.
•A load must never exceed the rated lifting capacity of the jack.
•Do not lift or support the vehicle with this jack. Place support stands under the vehicle
before starting repairs.
•Only use the jack on a hard, level surface.
•Center the load on the jack saddle. Off center loads can damage the seals in the ram and
cause jack failure.
•
Never move the jack with a load any higher off the ground than necessary. Slowly and
carefully move the jack around corners, because the load could tip. Stay clear of a lifted load.
•Lower the jack slowly and carefully while watching the position of the load.
•Do not modify the jack or use adapters unless approved or supplied by OTC.
•Use only anti-wear hydraulic jack oil with a 215 SUS viscosity rating at 100°F. The use of
alcohol, hydraulic brake fluid, or transmission oil could damage seals and result in jack
failure.
Setup Instructions
1. Remove the transmission jack from the pallet, and attach the casters using the hex nuts provided.
2. Remove the hex nuts holding the head assembly plate, and replace them with the wing nuts provided.
3. Remove the shipping oil plug, and replace it with the vented oil plug (Item No. 57) provided.
4. The reservoir tube is shipped filled with hydraulic oil. Before using the jack for the first time, press the release pedal
to open the release valve, and operate the hand pump eight full strokes to distribute the oil.
Operating Instructions
1. Follow the vehicle’s recommended service procedure for removal of the component.
2. Position the jack under the vehicle.
3. Raise the jack by operating the hand pump until the saddle touches the component.
4. Adjust the support brackets to fit the component.
5. Use the tilt crank to align the saddle with the component.
6. Finish raising the jack to the component. Secure the strap assembly around the component.
Maintenance
1. Use only anti-wear hydraulic jack oil. The use of alcohol, hydraulic brake fluid, or transmission oil could damage
the seals in the cylinder and result in jack failure.
2. Check the oil level periodically: lower the jack to its lowest position; remove the filler plug (Item No.. 57); add
hydraulic oil (215 SUS viscosity at 100°F) until the oil level is within 2" to 2-1/2" of the filler hole opening; install
the filler plug.
3. Lubricate the pivot points as needed with SAE 30 motor oil to prevent premature wear.
IMPORTANT: The greatest single cause of failure in hydraulic units is dirt.
Keep the jack clean and well lubricated to prevent foreign matter from
entering the hydraulic system.

Bleeding Air from the Jack
(Item numbers refer to the parts list on sheet 2, front and back.)
1. Retract the jack to its lowest position.
2. Remove the filler plug (Item No. 57). Fill the reservoir tube with hydraulic jack oil (215 SUS viscosity rating
at 100°F) to the correct fluid level of 2" to 21/2" from the top.
3. Remove the knob (Item No. 10) from the pump rod (Item No. 61).
4. Remove the end cap assembly (Item No. 60).
5. Disassemble the pump cylinder end (Item No. 17) from the pump cylinder (Item No. 62). IMPORTANT: Do
not let the pump cylinder turn during this step.
6. Fill the cavity with fluid, and reassemble the unit.
7. Operate the hand pump to extend the cylinder to a full stroke, and then retract.
Note: It may be necessary
to do this two or three times.
8. Check the fluid level again.

this equipment.
